To better understand if the pixelation is coming from your camera or from camtasia, you could try the following:

- If you have an iphone, record the same video with the iphone, import that into camtasia and see if the final product is pixelized - if so then Camtasia is responsible and you may want to play with the export settings.

- Use quicktime to record your 930, and see what the video looks like in that recording, if it looks good, bring it into camtasia and see how it looks after an export.

- Use Camtasia to record only your camera.Choose Share-> to file->MP4->Advanced Increase the bitrate to a crazy high number (this is just a test) and optimize for download, Entropy CABAC, Profile HighSee if the resulting file includes less pixelation - if so then export setting can be experimented with.

One or more of the above methods should help you get a feel for where the artifacting is coming from, and once you know the source, you can plan a route forward.

Note that if it does turn out to be your camera, there may be some things you can do to improve it.- Don't use/connect external USB storage when recording, as that competes for USB bandwidth.- Lower the resolution of the camera (I don't know if this is possible with the logitech control software, but if it is, try lowering the resolution to 1280x720)

Hello Jack - sorry for jumping into this late. I'm experiencing super pixelation with Camtasia and finally had some time to look into it. I downloaded 5 other video/screen recording software programs plus Quick Time. None of them have a pixelation problem with my C920. ONLY Camtasia has the problem. When recording the video on the on-screen looks fine - but after when it's in the video editor - even before exporting it - it is super pixelated. I thought it was my web camera and a system resource issue, but I now know it's just Camtasia. Whatever Camtasia is doing (still might be a resource issue), it destroys the quality of the video. Interesting side note, I recently made an HD video with Quick Time and one with Camtasia. The QT video was 1.7GB and the Camtasia video was 350MB for a similar, but not same 6 minute video. I don't know what affects the size, but it is interesting at best.

After evaluating all the difference software I could find, I still like Camtasia the best, but right now it's become unusable natively, and super cumbersome by using an external video recorder.

When recorded with Camtasaia 2.x I'm getting 1280x720 with an encoding rate of 30fps, and 1296kbps. Using Camtasia 3.x I'm getting 1600x868 with an encoding rate of 30fps and 1390bps (A second test had this at 1650kbps)

You can use the tool "Mediainfo" to examine the .trec files that Camtasia creates to look at the details of the capture.

I also tried this in Quicktime and it too exported a 1280x720 image. (though at a much higher rate of 10Mbps)

Thanks Jack. I think this is a well know problem based on my reading. At least one response blamed it on an OS encoding or driver problem which doesn't resonate with me since QuickTime works fine. Also, the pixelation is far more of a problem for me than the resolution. Neither have been resolved which really is inexcusable. I guess there are not enough Mac users to justify :/

Same problem here. Mac with a C920 webcam and the pixelation makes Camtasia unusable for me. Downloaded a trial of Screenflow and no problem, plug and play! Quicktime is perfect too, bit miffed because I bought the webcam thinking the built in camera was the issue but it's obviously Camtasia

I have the same issue with Camtasia 3.1.4 (103226) as of April 2018 so they did not fix it. Avoid Camtasia!!! I use Screenflow but it has another issue for the talking head videos. In Screenflow the audio gets out of sync with the video.
